Book on sneer-Mus c O ENER,

To all whom it may concern: Be it known that I, MABEL A. REILLY, acitizen of-"the United States of America, residing at Freeville, in thecounty of Tompkins and State :of. New York,'have invented certain newand useful Improvements in Book or Sheet-Music Openers, of which thefollowing is a specification.

The primary object of my invention is the provision of a book orsheetmusic opener adapted for retaining pages in spread out flat position foruse and easily adjustable for the changing of the pages, while thedevice is cheap and inexpensive to manufacture.

A further object of the invention is the provision of a device combiningpracti-v cability with simplicity and serviceable for such purposes asretaining music in its open arrangement upon an instrument or a musicrackwhile the same may also be employed .in connection with any .form ofbook that may be found desirable. 7

With these general objects in view and others that will appear as thenature of the invention is better understood the same consists of thenovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawing and then claimed.

In the drawing forming a part of this application, and in which likereference characters designate corresponding parts throughout theseveral views,

Figure 1 is a perspective view of a music book upon a rack held in itsopen position by means of my device;

Fig. 2 is an end elevation of the device mounted upon leaves of music,the device being indicated by dotted lines to show the manner ofdetaching the same as well as the fact that a greater number of leavesmay be readily held in position; and. r

Fig. 3 is a perspective view of. the de- 7 vice detached and partiallybroken away.

Referring more in detail to the drawing, my device comprises a holderformed of a single piece of wire of suitable resiliency so that the samemay be easily and quickly manufactured at a minimum expense.

The resilient wire is bent in the form of a central U-shaped loop 10with the adjacent portions of the wire extending from the opposite sides11 of said loop bent 1nto substantially triangular shaped formations 12when taken with the said sides of the loop.

Specification of Letters Patent. P t t d.J j Application filed-June 29.1918. swam. 1242,5154.

Oppositely projecting arms 13 constituting the end portions of the wire.at substantially opposite sides of the loop 10Iwith the arms 18 inaxial alinement with eachother and having termlnal beads 14 whichconstitute the extreme opposite ends of the device.

The I triangular portions .12 being readily grasped between the thumband forefinger of the personusing the device, the same may be easilyforced upon either the upper or lower ed e of a book or leaves, such asthe book 15, having a plurality of leaves 16, herein illustrated. inFig. 1, mounted uponthe usual form of music rack 17 which are employedby musicians, for instance in a band or an orchestra.

The loo 10 is positioned behind the book 15 with t 'e edge portion ofthe book entering the triangular portions 13 so that the arms 13 flatlyengage the leaves 16.

The beads 14; are in a plane substantially parallel with the plane ofthe loop 10 so as to flatly engage the exposed pages of the leaves whichare retained plainly viewable with the book open by means of the arms13.

It will be understood that the resiliency of the wire forming the deviceretains the same in its operative position upon the book or leavesuntiLit is desired to close the book or turn over one of the leavesthereof and at which time the device is readily removed and thereafterreattached in its operative position. 7

.It will be readily understood that the device maybe applied to books ofdifferent thicknesses and either to the top, bottom or one of the sidesthereof, while more than one device may be employed upon a single bookif desired.

While the form of the invention herein shown as described is believedjtobe the preferable embodiment thereof, it is nevertheless to beunderstood that minor changes may be made therein without departing fromthe spirit and scope of the invention as claimed.

.What I claim as new is 1. A device for holding a book distended withits pages flat together when the book is open comprising a central wireportion of substantially U shape adapted to lie the central portion andin the direction oi the length of the base of the latter to provide apair of relatively long arms adapted to bear against the two pages ofthe open' book for the Inajorportion of the width of said pages. 7 V i2. A devicefor holding a book distended with its pages flat togetherwhen the book is open-rcomprislng a central wire portion ofsubstantially U shape adapted to lie against theback of a'book at thecenter thereof, the ends of the Wire forming the s central portionextending in spaced relation 1 and at an inclination mayhem and thentoward the plane of said central portion to a point adjacent the base ofthe latter for engaging the two pages of the open book ad acent toa'ndat opposite sides of the center of the latter, the ends of the wirefurther extending in opposite directions in a'plane parallel to theplane of the centra-lportion and in the direction of the length of thebase of the latter to'provide apair of relatively long arms adapted tobear against the two pages of the ,open book. for the maj orportion ofthe width of said pages.v

In testimony whereof I aflix my-signature MABEL A; REILLY.
